Comment 1 Mike 2024-04-26 16:32:52 UTC
How is the printer connected?  Wireless or USB?

Do you have entries in `/etc/cups/ssl`?

Can you run `lpinfo -v` and paste the output here?

Can you remove the printer and try again, this time choose  the "Driverless" option when displayed?

If you cannot remove the printer from System Settings, you can try from the CUPS web GUI, `localhost:631`.

I have seen cases where the files in /etc/cups/ssl had to be removed and the cups service restarted before the printer would leave the "Paused" state.

Printed color page from CUPS and can view the print que from the system settings. From system settings I still cannot remove any printers, just pause and resume. When I print a page and choose a printer, all previously installed printers, even removed ones are available to choose.

Will try later

So, when click the configure button for the printer, you should be asked to authenticate, then you'll be at the printer settings page where there is a "Remove" option at the top.  When you click that Remove option, nothing happens?

This is going to be specific to the application you print from and might actually be that CUPS is "remembering" deleted printers and returning them as options for the apps.
